DIE FOR SHOE SOLES.

Application filed August 12, 1925. Serial No.. 49,790.

To all wlw/m, z't may comer/n:

Be it known that I, WILLIAM H. TAYLOR, a citizen of the United States, and resident of Upper Darby, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Dies for Shoe Soles, of which the following is a specification.

My present invention relates to a method of building shoes and more specifically of applying a' heel of the wood block type thereto.

The principal object of the invention is the saving of the initial amount of leather used in the outsole, and second, in the saving of time necessary to apply the heel thereto. i y' To this end my invention contemplates the cutting` out of the outsole in the manner which instead of including a bulbous heel, will be replaced by a substantially arrow headed portion over which the wood block heel will be fitted. The utilization of an outsole of this shape makes a substantial saving in the initial amount of leather required. v

It has been the custom after the outsole is secured to the upper, that the wood block heel be placed in position` by hand, the operator then taking a pencil or sharp instrumont and marking the outline of the breast of the heel upon the outsole, removing the heel, and with a knife trimming that p0rtion of the sole overlying the heel to form a tail piece, then applying the heel and securing the same by the usual glue, nail or screws.

This .invention further contemplates the use of a blade for automatically cutting the tail piece from the outs-ole in order to save this hand operation and thereby cheapen the cost of the shoe.

To this end the invention includes an anvil of metal which is adapted to be 4slipped beneath the loose heel of the outsole, and a blade of the proper contour which includes the curvature of the heel breast and the outline of the tail piece, land cutting the leather with this blade while resting upon the an-` vil, all of which is done automatically and in much less time than if these operations were performed by hand.

My invention further consists in the arrangement, construction and combination of parts hereinafter shown and described.

I have illustrated in the accompanying drawings a preferred form of the invention, although obviously I do not wish to be limited thereto.

In these drawings Fig. 1 is a front elevation of a device used to reciprocate the shoe against theanvil and knife. Fig. 2 is a composite view in perspective of a heel and heel portion of the s oe. Fig. 3 is a plan View of the shoe solo. Fig. 4 is .a plan view of the anvil. Fig. 5 is a side elevation of the device of Fig. 4. Fig. 6 is a sectional view along the line 6 6 of Fig. 4. Fig. 7 is a sectionalview along the line 7-7 of Fig. 4. Fi 8 is a front elevation of the knife, and plan View of the device of Fig. 8.

Referring now with particularity to the embodiment illustrated, I have shown an outsole as consisting of a toe portion 1, a heel portion 2, and a joining neck portion 3. Itwill be noted that the heel portion 2 is of substantially arrow shape and contour, the normal outline of the usual heel of an outsole being shown in dotted lines at 4. Obviously by using a heel having the contour as shown at 2, all of the leather included between the outline of said heel and the dotted line 4 is Vsaved in the initial cost of theshoe. This is a material item.

An outsole such as above described is shown attached to an upper as at 5 in the usual Way, and to which no claim is made.

At this point in the shoe building operation the heel portion 2 is loose and not positively secured to the upper. The securing of this portion of the sole to the shoe is by means of applying the heel thereto and passing a screw or nail from the inside through the wood of the heel.

In order toapply the wood block heel 6 it is obviously necessary that a portion of the heel portion 2 indicated by cross hatching and the numeral 7, must be removed therefrom in order to allow the outer edge of the heel 6 tolie adjacent the shoe upper at this point. Asl has been above stated, this is and draws a mark with a sharp instrument' across the breast of the heel adjacent the outsole. The shoe thus marked is then placed in a power machine of any desired type and to which no claim is made, in which is arranged an anvil comprising a shaft 8 secured in the machine, to the end of which is attached the anvil proper 9. This anvil is preferably of metal for a purpose more fully described hereinafter.

Above the anvil and arranged for vertical reciprocal movement is a knife comprising an arc shaped blade 10 and -two backwardly extending blades 11, the latter blades to cut from the heel portion 2 of the outsole the tail portion above referred to. That portion of the curved blade between the backwardly extending blades 11 is cut away and provided with a ilat face l2, the difference in level between the face l2 and the edges of the blades l0 and l1 being equal to the normal thickness of the outsole at the breast of the heel.

rIhe shoe at this stage of its structure is moved forward so that the anvil extends under the heel portion 2 of the outsole and then by suitable mechanism (not shown) the knife is made to move vdownward vertically so that the arc shaped blade 10 strikes the outsole along the line-indicated on the outsole as being the location of the heel breast. This downward movement of the blade will continue until the flat face 12 engages the surface of the outsole, when furthe-r down- 1 ward movement of the blade will be prevented thereby. At this point the blades 10 and 1l will have penetrated the outsole and severed off the pieces 7 so as to form the tail piece- 2a. The operator will then slightly bevel the edges of the tail piece with his knife, upon which it will be found that the heel 6 will exactly lit the curvature made by the arc shaped blade 10 and the heel maythen be secured to the shoe as in the ordinary manner. It will be noted in such a structure that the loose end of the outsole, namely the tail piece 2, is rigidly held by reason of the fact that it underlies the heel 6, or it may be tacked fast to the innersole or the shank piece, to which no claim is made.

Having thus described my invention, what I claim is 1. A die for fitting heels to shoes, including an arc-shaped blade of the curvature of the heel breast, said arced portion being interrupted by a non-cutting portion, and two straight blades extending backwardly from the arc-shaped portion at each end of the non-cutting portion.

2. A die for litting heels to shoes, including an arc shaped blade and two straight blades extending backwardly therefrom, that portion of the die between the straight -edges constituting a raised flat face.

3. A die for fitting heels to shoes, includ-v ing an arc shaped blade and two straight blades extending backwardly therefrom, that portion of the die between the straight edges constituting a raised flat face, the difference in level between the edges of the blades and the bottom of the fiat face being equal to the thickness of the outsole at the normal location of the heel breast.

In testimony whereof, I aliix my signature.

WILLIAM HEDGES TAYLOR.
